Why EPDM Roofs Fail
The same failure modes. Every time.
Membrane Shrinkage
EPDM shrinks over time, pulling away from perimeters, parapets, and penetrations. This creates gaps that no patch can permanently address.
Seam Delamination
EPDM seams bonded with contact cement fail after years of UV exposure and thermal cycling. Seam failures are the leading source of EPDM leaks.
Flashing Failure
EPDM flashings at walls, drains, and penetrations are the most vulnerable points on any EPDM system — and the first places shrinkage manifests.

EPDM Coating FAQ
Common questions about EPDM restoration
Yes, EPDM typically requires a primer to ensure proper silicone adhesion. We use manufacturer-specified primers and confirm adhesion testing before full-scale application.
Perimeter shrinkage and pull-away is exactly the failure mode silicone restoration addresses. We mechanically secure and reinforce the perimeter before coating. This is one of the most common EPDM restoration scenarios we handle.
Yes. White silicone coating transforms dark EPDM into a cool roof with 80–90% UV reflectivity. Facilities in warm climates typically see 15–35% reduction in cooling costs after restoration.
Silicone bonds to properly prepared and primed EPDM through chemical adhesion. Our crews clean the surface, apply manufacturer-specified primer, and confirm adhesion pull-tests before full coating application.
Ballasted EPDM can be restored, but ballast must be redistributed to allow surface prep and coating. We have experience with fully-adhered, mechanically-fastened, and ballasted EPDM systems.
